hello, I am conducting a research on biochar. But am in initial phase. I came to know that nitrogen use is important in biochar preparation for pyrolysis. Thus I need suggestion and help regarding the set up. I searched but couldn't find video about nitrogen setup. I am going to use isotemp muffle furnace 10-550-126 model. and exhaust port is 3/8 inch.
Should we supply nitrogen gas from exhaust port?
To produce biochar it is necessary to maintain oxygen free environment. And nitrogen is very much is used to purge the pyrolysis chamber.
In any muffle furnace there should be inlet and outlet port. Nitrogen gas could be purged through inlet port. You may attach some steel and ceramic made tube for inlet and outlet port, which is available in market.
Dear Babita Lamichhane
I had similar problem during my research, the outlet of the furnace was very wide and it was difficult to retain N2 environemnt. I put a rounded foil into the outlet point from inside the furnace and purged the N2 continously to have inert environment. If I had picture of your furnace I would have suggested you.
The other thing you can do is to produce the inert environment in the vessel you are using by purging sufficient amount of N2 and then sealing it.
Please put a foil into the outlet point from inside the furnace and purged the N2 continously to have inert environment
If you have tube furnace it would be best
